文章：
| Line | Suppose we were in a spaceship in free fall, where |
| objects are weightless, and wanted to know a small | |
| solid object’s mass. We could not simply balance | |
| that object against another of known weight, as we | |
| (5) | would on Earth. The unknown mass could be |
| determined, however, by placing the object on a | |
| spring scale and swinging the scale in a circle at | |
| the end of a string. The scale would measure the | |
| tension in the string, which would depend on both | |
| (10) | the speed of revolution and the mass of the object. |
| The tension would be greater, the greater the mass | |
| or the greater the speed of revolution. From the | |
| measured tension and speed of whirling, we could | |
| determine the object’s mass. | |
| (15) | Astronomers use an analogous procedure to |
| “weigh” double-star systems. The speed with which | |
| the two stars in a double-star system circle one | |
| another depends on the gravitational force between | |
| them, which holds the system together. This | |
| (20) | attractive force, analogous to the tension in the |
| string, is proportional to the stars’ combined mass, | |
| according to Newton’s law of gravitation. By | |
| observing the time required for the stars to circle | |
| each other (the period) and measuring the distance | |
| (25) | between them, we can deduce the restraining |
| force, and hence the masses. |
题目：
Which of the following best describes the relationship between the first and the second paragraph of the passage?
选项:
A、
The first paragraph provides an illustration useful for understanding a procedure described in the second paragraph.
B、
The first paragraph describes a hypothetical situation whose plausibility is tested in the second paragraph.
C、
The first paragraph evaluates the usefulness of a procedure whose application is described further in the second paragraph.
D、
The second paragraph provides evidence to support a claim made in the first paragraph.
E、
The second paragraph analyzes the practical implications of a methodology proposed in the first paragraph.
答案:
A
提问：
想问郭老师，这题要怎么判断选项？
我读出来两段间的关系就是两个procedure类比的关系。B我觉得错在 hypothetical，第一段不是一个假说；D我觉得两段不是evidence和claim的关系；C不知道错在哪里；E也不知道错在哪里，我选了E，我觉得说第二段是第一段所说方法的一个应用好像也没有问题，他们不是差不多的过程吗...
